And hell YES the FM2 is worth it, so much so I've bought two of them
(I broke my first one).
But be careful if you end up buying one from the US and don't live there (and vice-versa perhaps?), I live in Ireland and was landed with a customs tax of €60 which i had to pay the UPS man at my front door, that was quite un-nice. But it's a fantastic camera, it's knobs and dials are in the best places and it's got the best kind of focusing screen. Also it's near-indestructible - I only managed to break mine cos I'm supremely careless with my stuff (also other people's stuff). If you want some better examples of what the FM2 can do you should check out bebrit's home, she's done some pretty amazing stuff..
Tanks for the comments too!
